Wheel type elevating cutter-head mower

Abstract

The invention discloses a wheel type elevating cutter-head mower. The mower includes a chassis walking device, a mowing device and two sets of height adjusting devices; the chassis walking device includes a front axle, a rear axle, a vehicle rack, walking wheels and walking power mechanisms; the mowing device includes a rack, cutting knives and a driving mechanism; each height adjusting devices includes two linking rods in parallel arrangement, a connecting rod and an electric push rod; each linking rod is provided with three hinge joint which include an upper end hinge joint, a middle hinge joint and a lower end hinge joint; the lower end hinge joints are in hinged joint with the rack, and the middle hinge joints are in hinged joint with the vehicle rack; the two ends of each connecting rod are respectively in hinged joint with two upper end hinge joints; and one ends of the electric push rods are in hinged joint with the vehicle rack, and the other ends of the electric push rods arein hinged joint with the upper end hinge joints of the linking rods. The mower can realize the adjusting of heights and relieve the gravity that the electric push rods bear, so that damage to the electric push rods due to fatigue can be avoided, and the service life of the mower can be prolonged.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a wheel-type liftable cutter head lawnmower. Background technique [0002] Lawn mower is the most commonly used a kind of mowing equipment in the prior art, and lawn mower is also called weeder, lawnmower, lawn trimmer etc. A lawn mower is a mechanical tool for mowing lawns, vegetation, etc. It is composed of a cutter head, an engine, a walking wheel, a walking mechanism, a blade, a handrail, and a control part. The cutterhead is installed on the walking wheel, the cutterhead is equipped with an engine, and the output shaft of the engine is equipped with a blade. The blade uses the high-speed rotation of the engine to increase the speed a lot, which saves the working time of the weeding workers and reduces a lot of human resources. [0003] With the continuous development of science and technology, modern lawn mowers have become more and more mature, but there are also some...

AI Technical Summary

Problems solved by technology

But above-mentioned lawn mower has the following disadvantages: because the grass breaking device is connected on the primary electric push rod through the power transmission plate, the electric push rod needs to bear the full gravity of the grass breaking device. The gravity of the grass device makes the electric push rod in a continuous load state, which will easily cause fatigue of the lifting motor and the first-level electric push rod, and cause damage to the lifting motor and the first-level electric push rod
